Catalytic converter in vehicle is used for controlling

Options

A. Air pollution
B. Water pollution
C. Radioactive pollution
D. Soil pollution

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks about the function of a catalytic converter in vehicles and its role in controlling different types of pollution.

2. **Identifying Pollution Types**: The options provided are air pollution, water pollution, radioactive pollution, and soil pollution. We need to determine which type of pollution the catalytic converter addresses.

3. **Function of Catalytic Converters**: Catalytic converters are devices fitted in vehicles that help reduce harmful emissions produced during fuel combustion. They contain metals, primarily platinum, which facilitate chemical reactions.

4. **Chemical Reactions**: Inside the catalytic converter, harmful substances such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons are converted into less harmful substances. For instance:
- Carbon monoxide is converted into carbon dioxide (CO2).
- Nitrogen oxides are converted into nitrogen (N2) and oxygen (O2).
- Hydrocarbons are converted into carbon dioxide and water vapor.

5. **Conclusion**: Since the catalytic converter specifically targets emissions from vehicles that contribute to air pollution, we conclude that the correct answer is air pollution.

6. **Final Answer**: The catalytic converter in a vehicle is used for controlling air pollution.
